For titration. Hardness in water is mainly due to the presence of calcium and magnesium ions and each contributes to the amount of total hardness. Monitoring and controlling hardness is instrumental in preventing scaling and corrosion. The reagent is then added under monitored conditions.
During testing, when colour change is achieved, under careful conditions - usually using a burette � the reagent is added, drop by drop, until the solution turns clear. The user will then count how many drops of reagent were used to achieve complete colour dispersal. The number of drops used will determine the chemical concentration and results can be found in the manual included.
